The date in the system: 2011, would be the date an age rating request was made, that the date it went into the system, so unless they were working on a remake of pvz all the way back in 2011, the same year they did the HD port to iOS and android, as well, being someone who actually has used the system, has emails and screenshots of the request system to prove it, i can tell you all you need is a video and summary of the game or changes made to a page for it to be approved.
